Paper Abstract

The thermo-induced absorption spectrum was demonstrated, for the first time, to be a useful technique for the study and identification of impurity levels in photorefractive crystals. With this technique, the absorption peak generated by the Ce-doping in BaTiO3:Ce was revealed and identified, the related impurity level and the optical transition were determined.
